* Axle Ratio: Different axle ratios were available, significantly impacting towing capacity. Higher numerical ratios (e.g., 4.10) allowed for better towing performance than lower ones (e.g., 3.07).
* Transmission: The type of transmission (manual vs. automatic) also affected towing capacity.
* Options: Additional options like heavy-duty suspension packages or different tire sizes could slightly alter the capacity.
* GM Documentation Discrepancies: Finding consistent and reliable towing capacity information from original GM documentation for these older vehicles can be difficult.
Therefore, you can't find a precise number without knowing the specific configuration of the particular 1982 K5 Blazer.
To get a reasonable estimate, you should:
1. Check the owner's manual (if available): This is the best source.
2. Look for a sticker on the vehicle: Sometimes there was a sticker on the driver's side doorjamb or elsewhere indicating the GVWR (Gross Vehicle Weight Rating) and perhaps a towing capacity.
3. Consult a reliable parts catalog: Some online catalogs specific to classic Chevrolet vehicles might list variations in towing capacity based on options.
Keep in mind that even with this information, the stated towing capacity is a maximum. Several factors such as terrain, weather, and cargo weight within the vehicle will reduce the safe and practical towing capacity. It's always best to tow conservatively.
